MIXING DEVICE FOR EXI'DLOSIVE-ENGINES.

sPEcIFrcATIoN forming part of Letters Patent No. 683,749, dated october 1, 190i. Application filed January 5, 1900. Serial l-To. 496. (No model.)

To @ZZ whom, it may concern,.-

Beit known that I, NARCISSE ALEXANDRE GUILLAUME, a citizen of France, residing at 15 Rue du Louvre, Paris, France, have invented certain new and useful Improvements in Mixing Devices for Explosive-Engines, of which the following is a specification.

The object of this invention is to provide, in connection with explosive-engines, apparatus for producing an explosive mixture of air and gas wherein the proportions of air and gas will be the same whatever may be the volume of mixture drawn into the engine.

According to my invention the apparatus consists, essentially, of a compartment openbottomed closure or bell, combined with a compartment receptacle or casing, the former telescoping the latter and suitably air and gas tight sealed therein. The respective capacities of the compartments of said parts are to be proportionate to the volume of air and gas mixture irrespective of the altitude to which the bell or closure may rise. The height or depth measurement of these compartments is the same or equal. Consequently these conditions will be fulfilled if their crosssectional areas be such that the ratio between them be the same as that between the volumes of gas and air for mixing.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a vertical section taken on the line A B C D of Fig. 3. Fig. 2 is a horizontal section on the line E F ot Fig. l. Fig. 3 is a vertical section on the line G H of Fig. 1. Fig. 4 is a compound section, one portion of said section being taken on the line I J and the other portion taken on the line K L of Fig. 1. Fig. 5 shows in side elevation the connection of my device with an explosiveengine of the kind described in Letters Patent No. 661,865, granted to me on November 13, 1900; and Fig. 6 is an end view of the same. A

Latitude is allowed herein as to details, as they may be changed according as the judgment may dictate without departing from the spirit of my invention and the same yet remain intact and be protected.

In carrying out my invention I employ 'a casing or receptacle d and a bell or open-bottomed closure f, telescoping the former. Said casing is subdivided into a number of compartments a b c, two of which, a b, are closed and designed to be filled with air and gas, the other, c, being open and without function in the operation of the device, and said bell or closure is also subdivided into a like number of compartments g 7m', the compartments c, and b communicating with the compartments g h. Said bell or closure has also a raised or root compartment or passage j unconnected with its compartment g, relatively central thereof; but said compartment j has communication via end openings with the compartment h and the air passage or ductt of the receptacle d, delivering air to the engine, respectively, as disclosed by Figs. l and 4.

Within the walls of the casing d and of the compartment walls thereof are provided spaces'or chambers e, adapted to receive the walls of the bell or closure f and its compartment-walls, as shown, and within said spaces or chambers is designed to be placed mercury or other suitable material to form a gas and air tight seal for said bell or closure. The compartments h and t, being connected by the roof-passage j, form a continuous or single chamber or compartment for the passage or conduct of the air therethrough on its way to the engine.

The chamber aand the compartments h and i are for the reception of air, while the chamber b and the compartment g are for the reception of gas. Communication between the compartments b and g and a, and h, respectively, is effected or provided for via apertures controlled by spring-pressed valves m and n, whose stems m' and n are connected by means of links or levers m2 n2, respectively, to a shaft k, on which these levers are keyed, which shaft is operated by the motor or engine, as hereinafter described.

Projecting from the sides of the casing d and bell f are eyes o, o', and p, respectively, through which pass rods q, encircled by springs rr', bearing at their lower ends upon the eyes o on the lower end of the casing d, the upper ends of said springs bearing upon the eyes p. The action or tension of these springs is adjustable by means of screw-nuts IOO p', the object of said springs being to raise said bell or closure to its proper height after it has been caused to descend.

Air enters the chamber a through a conduit or pipe s, Fig. 2, and passes by the valve lninto the compartment h of the bellf, thence through passage j into the compartment 1l, and therefrom through the vertical channel tto the engine. The gas enters the chamber b through a conduit or pipeuand, Figs. 2 and 3, passes by the valve m when opened into the compartment g of the bell fand therefrom through a vertical conduit or pipe o, Fig. 3, to the engine. The respective capacities of the compartments in the bell should have the same relative proportion as exists between the air and gas used to form the mixture. These c0mpartments g, h, and fi are the same in height above the compartments a, b, and c. Therefore in order to insure the desired relation between their respective capacities and their horizontal areas combined it is only necessary that the horizontal areas of the gas-compartment g and of the air-compartments h and i combined should be proportional to the volumes of gas and air, respectively, forming the mixture, and inasmuch as all the compartments g, h, and t' move at the same time and have the same amount of movement this proportion will be maintained Whatever may be the height of the bell above the compartments 0L, b, and c. r

I shall now describe the operation of the device in connection with an explosive-engine of the kind described in Letters Patent granted to me, No. 661,865, this connection being illustrated in Figs. 5 and 6 in side and rear elevation, respectively. In these figures tl o are pipes conveying, respectively, the air and gas issuing from the pipes tlv to the box 1, containing the inlet-valve of the engine, in which box the air and gas are mixed together, the said inlet-valve being controlled by means of the cam 4, keyed on shaft 2, and bell-crank lever 3 3. 5 represents the box containing the exhaust-valve, which latter is controlled by means of the cam 6, keyed on shaft 2, and bell-crank lever 7 7. On the same shaft 2 is keyed another cam 8 in the opposite direction-that is to say, one hundred and eighty degrees-to that of the cam 4, said cam 8 operating by means of bellcrank leverg g and link 10 the lever 7c', keyed on the shaft 7a, Fig. 1, which cooperates with the valves m n, as already explained. New let it be supposed that bell-compartments h and fr' are filled with air and gas and that the suction action of the engine is about to be exerted. The form of the cam which operates the aforesaid link 10, and therefore through intermediary of lever la', shaft k, and links 'm2 n2 the stems m and n', is such that during such suction action the valves m and n are open and air is drawn into the chamber a through pipe s and gas is drawn into the esame chamber b through pipe u. The pressure of the air and gas in the compartments decreases, While the atmospheric pressure acting upon the top of the bell causes such bell to descend, the springs r being compressed in the act. During the two phases of operation which follow said suction action the valves m and n continue open, the springs reir.-`

pand and the bell f rises, the gas from the compartment b lls the compartment g, and air from the compartment a passes into the combined compartments h and i until the bell is moved upward to the maximum limit. During the third'phase of operation following the suction the valves m and 'rt are kept closed by means of the described arrangement of levers m2 n2, spindle 7s, lever Zo', link 10, and cam. At this juncture suction action is about to again be exerted, and a repetition of the foregoing cycle of operations takes place.

Having now particularly described and ascertained the nature of this invention and in what manner the same is to be performed, I declare that what I claim is- 1. In apparatus of the character described, the combination of a compartment or subdivided casing or receptacle having suitable air and gas inlets and outlets, and Whose chambers or compartments are provided with valve-controlled openings or passages, a subdivided or compartment movable closure or bell having one chamber or compartment communicating with a distant compartment or chamber of said bell and an intermediate chamber or compartment thereof communicating with a corresponding chamber or compartment of said receptacle or casing, and means to provide for the return movement of said bell after its descent, substantially as set forth.

2. In apparatus of the character described, the combination of the receptacle or casing having a series of compartments or chambers provided With air and gas inlets and outlets and valve-controlled passages or openings, a movable closure or bell having a series of compartments or chambers, one of the end compartments of said bell communicating Withone of the compartments of said casing and the intermediate compartment or chamber communicating with the like compartment or chamber of said receptacle or casing,- and means to provide for the return movement of said bell after its descent, substantially as specied.
